Source is prepared by separating the elements of tuples by adding
". " with items 0 and ", " with items 1 of the plural
tuples(where " " serves as a level 1 separator and "."
& "," serves as level 2 separators) and then concatenating them
as a whole.

Using this source we can separate the item 1 and item 0 of plural tuples
to perform operations.

q:(substrings separated by " "ofit) of"2. 2, 22. 226, 222. 111,"

A: 2.

A: 2,

A: 22.

A: 226,

A: 222.

A: 111,

T: 0.076 ms

I: plural substring

" "(LEVEL 1 SEPARATOR) is used to get the various elements
individually along with the level 2 separators attached to them.
